Ya sanding is a pain. A few years ago I bight my mom one of the black and decker cyclone sander things (she's into wood work) and I used that when painting my trunk lid of my old avenger. It came out smooth, but what I didn't like was it wound up having no gloss look at all. Not sure if it was because of the clear, or because I needed to wet sand afterwards or something. Either way that's what's keeping from doing my civic. I may start with something small like jus the bumper to see how it turns out. Both my bumpers could Use it anyays, they have a lil road rash after 10 yrs.
